Application August-13, 1947, Serial No. 768,369 11 Claims. (01. 226-126) COMBINED DELIVE V The invention relates to a combined delivery tube nozzle and valve principally intended for handling granular materials from a storage bin, more especially dry sandfr'om storage to diesel, steam or electric locomotives.

The invention is in the nature of. an improvement on the combined nozzle and valvedisclosed in an application filed May 16, 1947, by Max W. Powell, Serial No. 748,464, now Patent No. 2,566,248, dated August 28, 1951, andit will be understood that the present deviceis primarily intended for use in an assembly such as is disclosed in Fig. 1 of that application, as a substitute for the combineddelivery tube and nozzle H thereof, wherein the said combined delivery tube, nozzle and valve is shown as connected with the lower end of a flexible tube or conduit communicating at its upper end with a sand supply tank or bin, and is adapted to automatically open to discharge sand into a locomotive said box by reason of contact between a portion of the device and the wall of the sand box, and is adapted to automatically close as soon as the nozzle is removed from the sand box, thus avoidin wastage and loss of sand, although it will be apparent that the improved nozzle and valve may also be used in other relations without departing from the spirit of the invention in its broadest aspects.

My improved delivery tube nozzle and valve preferably consists of two principal parts, (1) a main body portion comprising a tube adapted to be connected at its upper end to a delivery pipe or spout leading from an elevated storage tank or bin, said tube being. equipped with a sealed lower end, a valve seat and a weather shield, and (2) a normally closed gravity acting slide valve fitting over the body portion and equipped with a locking handle and operating horn.

The invention will be more readily understood by reference to the accompanying drawings and the following detailed description, in which is set forth by way of illustration a specific embodiment of the inventive thought.

In the drawings:

fragmentary section on Referring to the drawing, the valved nozzle includes two principal ,partsa main body portion A comprising a tube with a sealed end, a valve seat and a weather shield secured thereto, and a normally closed gravity acting tubular slide valve member B equipped with a locking handle and an operating horn.

As shown the main body A comprises a tube I I open at its upper or inlet end and adapted for attaching to a flexible hose 2 or the like corresponding to the tube ,A of Powell Patent No. 2,566,248, and closed at its lower or outlet end by a circularplate 3 which may be welded into the end of the tube I. As shown a centering filler plate 4 is fastened to the closure plate 3. A sealing ring 5 of rubber or suitable composition material is slipped over this centering plate and held in place by means of a circular retaining plate 6 and a bolt 1 to form a seatfor the end of the tubular sliding valve B. An opening 8 is cut into the lower end of the main body tube 1 of suflicient size to equal the area of the tube section.

Near the upper or open inlet end of the main body tube 1 a filler collar 9 is weldedor otherwise secured to support a weather shield l0 which comprises a tube of large enough internal diameter to fit loosely over the tubular'sliding valve member B. A slot l l is cut into the lower end of the weather shield I0, into-which an operating horn l3 carried by valve member B slides. Near its lower end the slot H is enlarged to provide rectangular recesses 12 in the lower edge of the weather shield, thus forming a straight shoulder 16 extending laterally from the side of the slot II, which shoulder coacts with the rear end of the horn l3 to provide a latch for retaining the slide valve B in its lowered or closed position, the latching operation being effected by rotating the horn away from the slot ll out into the lateral recess 12.

The slide valve member B comprises a tube ll of a diameter and gauge suflicient to fit freely over the inner main body tube l and loosely into the weather shield tube 10 carried by the body tube. The lower end of the slide valve tube H is preferably lathe-cut to form a smooth internal beveled edge which fits evenly and snugly against the sealing ring 5 at the lower end of the main body tube when the Valve is closed and latched.

To the slide valve tube I4 the operating horn I3 is welded, which horn includes a steel bar which runs back along the tube I to serve as a guide in cooperation with the slot ll while the rear or upper end of the horn coacts with the shoulder l6 formed by the notch I2 in the I weather shield 10 in the locking operation. To

this bar is welded a steel rod 20 providing a handie l5 at its rear, or upper end for easy operation of the valve. The front or lower end of the rod 20 is downwardlyand forwardly inclined aseat -Zl in a direction substantially parallel tothe.

front end of the horn member [3. The space between these two forwardly and downwardly inclined ends is sufficient to fit over a portion of an upright Wall I, which may be a side Wall of the locomotive sanding box as set forth in application Serial No. 748,464.

In service the operator may raise the device by the main body A, insert the nozzle into a receptacle such as the locomotive sand box I disclosed in Patent No. 2,566,248, with the upturned portion of the operating horn l3 resting against the edge of the receptacle, unlock the slide valve B by a slight rotation of the handle I5 and push the main body tube forward, thus opening the slide valve. When sufiicient material has been delivered from the hose 2 the operator grasps the valve handle l5, pulls back on the main body tube I and, assisted by gravity, pushes the slide valve B closed. A slight rotation of the handle I 5 looks the valve in closed position.

It will be apparent that the shield l0, including the filler collar 9, serves the function of providing a waterproof housing for the sleeve valve B, which valve slides freely in the space provided between the body tube l and the shield I [within longitudinal limits provided by the lower end of the collar 9 on the one hand, and the sealing ring 5 on the other, the said collar '9 and shield I preventing access ofwater from above'into the space between the shield 10 and the tube 1 in which the valve B slides, and thus preventing corrosion and sticking of the slide valve B, which valve, owing 'to its weight and the downward inclinatlon of the hose supported main body tube I, on which it slides, willnormally occupy a closed position when the nozzle is not in use. The notched lower end l2 of the shield or housing 10 in cooperation with the upper end of the horn I3 also provides means for locking the valve in closed position as previously set forth, the'lower end ofth'e slide'valve being snugly engaged with the compressible sealing ring 5 carried by the tubular body member to insure a sand tight fit.

A specific embodimentot the inventive thought has been described in'detail for the purpose of illustration, but it will be obvious that numerous modifications'and variations may be resorted to without departing from the spirit of the invention.
